The present paper studies the prospective and the performance of a forthcoming high-speed third generation (3.5G) networking technology, called enhanced uplink, for delivering mobile health (m-health) applications. The performance of 3.5G networks is a critical factor for successful development of m-health services perceived by end users. In this paper, we propose a methodology for performance assessment based on the joint uplink transmission of voice, real-time video, biological data (such as electrocardiogram, vital signals, and heart sounds), and healthcare records file transfer. Various scenarios were concerned in terms of real-time, nonreal-time, and emergency applications in random locations, where no other system but 3.5G is available. The accomplishment of quality of service (QoS) was explored through a step-by-step improvement of enhanced uplink system's parameters, attributing the network system for the best performance in the context of the desired m-health services.

Assessment Factor

Composites are cutting edge engineering materials for modern high-technology products. Their heterogeneous structure entails processing defects uncommon with metallic parts. Drilling is a crucial manufacturing process to facilitate fastening and assembly of composite components. High-speed drilling especially is a promising technique to increase the productivity as well as the quality of the drilled hole. The severity of delamination damage around the drilled hole is a critical factor in the error-free performance of these parts in service. A new method to characterize the delamination induced by drilling with a comprehensive assessment factor called effective equivalent delamination factor is developed to overcome the limitations of other measures being used hitherto. The capability and appropriateness of effective equivalent delamination factor as a delamination assessment factor are verified from experimental results.

The digital image, character/texts, audio (music), and video are the multimedia contents commonly used as objects to be transmitted on the VLC system. This paper has performed the real-time file transfer successfully using VLC technology with a UART connection. The FPGA was chosen as a DSP due to its capability in clocked-speed. We used an Ethernet connection due to its easy configuration and ability to meet the high-speed communication requirement. It was used for communicating between the host and the client device computer. This work covers the MAC layer implementation, SoC FPGA for UART connection, and analog front-end (AFE) transceiver. According to the functional test, the achieved bandwidth of the Ethernet connection is about 83.6 Mbps. However, the FPGA’s clock is set at 100 kHz only due to the transferred file does not require a high speed. Thus, the physical layer baud rate is fixed to 11520 bps; it can be used for real-time transfer of a digital image with 512 pixels with no compressed file and error at 22 cm of optical LoS channel (no lenses).

Time Calculation

Both safety and efficiency should be considered in high-speed train following control. The real-time calculation of dynamic safety following distance is used by the following train to understand the quality of its own following behavior. A new velocity difference control law can help the following train to adjust its own behavior from a safe and efficient steady-following state to another one if the actual following distance is greater than the safe following distance. Meanwhile, the stopping control law would work for collision avoidance when the actual following distance is less than the safe following distance. The simulation shows that the dynamic control of actual inter-train distance can be well accomplished by the behavioral adjustment of the following train, and verifies the effectiveness and feasibility of our presented methods for train following control.

PurposeIn the domain of healthcare, both process efficiency and the quality of care can be improved through the use of dedicated pervasive technologies. Among these applications are so-called real-time location systems (RTLS). Such systems are designed to determine and monitor the location of assets and people in real time through the use of wireless sensor networks. Numerous commercially available RTLS are used in hospital settings. The nursing home is a relatively unexplored context for the application of RTLS and offers opportunities and challenges for future applications. The paper aims to discuss these issues.Design/methodology/approachThis paper sets out to provide an overview of general applications and technologies of RTLS. Thereafter, it describes the specific healthcare applications of RTLS, including asset tracking, patient tracking and personnel tracking. These overviews are followed by a forecast of the implementation of RTLS in nursing homes in terms of opportunities and challenges.FindingsBy comparing the nursing home to the hospital, the RTLS applications for the nursing home context that are most promising are asset tracking of expensive goods owned by the nursing home in order to facilitate workflow and maximise financial resources, and asset tracking of personal belongings that may get lost due to dementia.Originality/valueThis paper is the first to provide an overview of potential application of RTLS technologies for nursing homes. The paper described a number of potential problem areas that can be addressed by RTLS.

The work proposes and investigates an intelligent method and algorithms for on-line assessment of the state of network elements to ensure the required quality indicators of provided communication services in corporate high-speed multiservice communication networks. The developed method and algorithms operate in a mode close to real time. One of the features of corporate multiservice communication networks is the high dynamics of changes in their state. The main task of the automated control system, which is an integral part of the corporate multiservice communication network, is to ensure the specified quality of the provided communication services to the consumer. Thus, the relevance of the research presented in the work is due to the fact that most of the management processes in corporate high-speed multiservice communication networks must be implemented in a mode close to real time with a given quality. The basis of the method for operational assessment of the state of network elements is the concept of creating and using intelligent agents. In the proposed approach, intelligent agents are created as hierarchical fuzzy situational networks, in which control solutions, in contrast to known methods based on the use of reference situations, are applied based on solving a hierarchical set of optimization problems using fuzzy mathematical programming methods. The main paradigm of their functioning is “situation -action”.

Quality Of Health Services

Abstract. The quality of health services depends on the contribution of all the professionals involved in the system, including certain groups, usually forgotten and underrated, such as the health-transport technicians (HTT). With the aim of improving this group's performance, an intervention program, focusing on the development of the workers' technical and social skills, was designed in a collective of enterprises. Information about the first stage of this program, consisting of the assessment of these workers' social skills, is offered in this study. A specific questionnaire was developed: The Health-Transport Technicians Social Skills Questionnaire (HTT-SSQ), made up of three scales (assertive, passive, and aggressive behavior). It was administered to a large sample (N = 530) from the above-mentioned association. The psychometric properties of the questionnaire were analyzed, with quite satisfactory indexes of internal consistency and factor validity, and the group's deficiencies (excess or deficit) were evaluated.

It has been known that both in the world and in Turkey a continuous change has been experienced in the provision of health services in recent years. In this sense by adopting the customer(client) focused approach of either public or private sector hospitals; it has been seen that they are in the struggle for presenting a right, fast, trustuble, comfy service. The purpose of this research is to measure the satisfaction degree, expectations and perceptions of the patients in Karabük State Hospital through comparison. In this context, the patient satisfaction scale which has been developed as a result of literature review has been used and by this scale it has been tried to measure the satisfaction levels of the patients in terms of material and human factors which are the two main factors of the service that was presented. In the study, with the scales of Servqual and 0-100 Points together, in the part of the analysis MANOVA have been used. The expectations and the perceptions of the patient has been compared first by generally and then by separating to different groups according to the various criterias and in thisway it has been tried to be measured their satisfaction levels. According to the results that were obtained, although, the satisfaction levels of the patients who have taken service from Karabük State Hospital are high in terms of thedoctors and the nurses; it has been reached to the result that their satisfaction levels are low in terms of the materials that have been used at the presenting of the service and the management.
